Calibration Traceability

Apogee Instruments SQ-600 series quantum light pollution sensors are calibrated through side-by-side comparison

to the mean of four transfer standard quantum light pollution sensors under a reference lamp. The transfer

standard quantum light pollution sensors are recalibrated with a quartz halogen lamp traceable to the National

Institute of Standards and Technology (NIST).

± 5 % (see Calibration Traceability below)

340 to 1040 nm ± 5 nm (wavelengths where response is greater than 50 %; see Spectral

± 2 % at 45° zenith angle, ± 5 % at 75° zenith angle (see Directional Response below)

Anodized aluminum body with acrylic diffuser

-40 to 70 C; 0 to 100 % relative humidity; can be submerged in water up to depths of 30 m

5 m of two conductor, shielded, twisted-pair wire; TPR jacket; pigtail lead wires; stainless steel
